I dont think Samsung Galaxy S4 would survive Sony's Xperia Z erra!.... 2013 is for xperia z because people want to see new features like water proof, dust proof, unbreakable screen etc.... I think xperia z has already outsmarts the so called upcoming S4.... Always try new things... thats how life goes on

guys! I will tell u one thing for certain de s 4 will not have a spen for sure and will hav a homebutton and defenately is coming with exnos 5 octa where one A15 cortex quad and one aAv cortex quad .It is coming with android 5.0(key lime pie) and not with 4.2(jelly bean) i.e. Why der has been a delay in the launch,it was actually going to be released in febuary first week but got delayed due to dis reason.It wud hav a like s 3 wer de front camera lools at ur i and will scroll de screen automatically and wireless charging will be der but sold seperately(15 days aftr de launch) and those of u who think s 4 is too big for u,dont worry 's 4 mini' is releasing in may at a cheaper price and der is even going to be a releasment of an android watch also as samsungs anwser to apple's Iwatch

I have got dis information from samsung HQ its self and asure it.
Thank u

pokhara_guy, 15 Feb 2013no way its gonna be a quad core 2 ghz that also a15. Battery should be like 4500mah then It will be probably a 1.8 GHZ Octa core. It will have 4 A15 cores at 1.8 GHZ for games, and 4 A7 cores for lower tasks such as sms for example.
